[SMM New Energy Flash News] Nigeria faces a growing environmental and public health crisis due to the improper disposal and crude recycling of used batteries, especially lead-acid and lithium-ion types. In cities like Aba, batteries are often discarded in dumpsites where rainwater washes toxic heavy metals such as lead, mercury, and cadmium into soil and groundwater, leading to kidney disease, neurological problems, developmental delays in children, and even cancer. Despite the government’s introduction of the National Environmental (Battery Control) Regulations 2024 and Extended Producer Responsibility (EPR) programmes, poor enforcement and the dominance of informal recycling sectors have left millions exposed to hazardous contamination. Experts stress that only through stronger regulations, proper recycling infrastructure, public awareness, and international cooperation can Nigeria address the environmental, health, and economic costs, which amount to billions annually.
